面向差异化电力物联业务的分层级网络队列调度算法
Hierarchical Network Queue Scheduling Algorithm for Differentiated Power IoT Services
摘要
Abstract
With the rapid development of network technology and the continuous expansion of power grid scale,power grid smart terminals and sensors and other devices are deployed on a large scale at power sites.The amount of power grid data is growing exponentially,and the types of business data are becoming increasingly rich.Different priority services have different requirements for key indicators such as delay,packet loss rate,bandwidth,etc.The traditional Internet of Things network is still insufficient in guaranteeing differentiated services for high priority services.Therefore,it is necessary to focus on the effective scheduling of power IoT business data.Traditional IoT networks are designed for non real time data transmission and provide"best effort"services,which are difficult to meet the service quality requirements of different businesses.This paper balances real-time and fairness,considers delay jitter coefficient and historical traffic density,and improves the strict priority(SP)algorithm and the deficit weighted round robin(DWRR)algorithm.By dynamically adjusting the polling weights,an improved deficit weighted round robin strict priority(IDWRR-SP)business scheduling multi priority queuing model is proposed to optimize transmission performance.The simulation results have demonstrated the effectiveness and feasibility of the algorithm,greatly ensuring the real-time requirements of high priority services and fair scheduling of low priority services.关键词
